Which country produces the hottest porn?

I do not watch much porn other that the clips from PornHub and its sister sites.

From what I have seen it seems like Europe has a lot of Porn of Older Woman with younger Guys and Vice Versa and Japan has a lot of porn that includes lots of oil and massaging. Oh yeah and they blur all good parts of the body making the porn a turn off.

For those of you that know a lot about porn which country do you believe produces the hottest porn?
